The AirTAC GFR300C10ALC2W AirTAC Filter Regulator PT3/8, 5 um is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR300C10ALC2W is a filter regulator: it removes water and particulate from compressed air and holds a set downstream pressure, both in one body. This configuration is built on the GFR300 size with PT3/8 (3/8 in) ports, the 5 um filter element (code W), an automatic drain on the metal bowl, and the low-pressure regulator type for circuits that run below standard line pressure. It is supplied with the external round gauge reading in psi and a mounting bracket; no reverse (check) valve is fitted.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options across drain type, 40 um or 5 um filtration, gauge style and scale, G or NPT threads, and bracket choice. Flow is published as curves rather than a single rating, and the exact adjust range of the low-pressure type is not a published figure, so ask us to confirm both from the datasheet against your application before ordering.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Feeding filtered, regulated air to the pick-and-place cylinders and grippers on a carton packing line, with the 5 um element protecting directional valves from particulate and the automatic drain clearing condensate without daily attention.
Holding a steady, lower set pressure to a clamping fixture or small press on a machining cell, where the low-pressure regulator type matches circuits running below standard mains pressure and the psi gauge gives operators a direct readout at the machine.
Supplying regulated air to gate and divertor actuators along a bottling-line conveyor, with the metal bowl and automatic drain handling condensate in continuous-duty areas and the included bracket simplifying mounting beside the line.
Choose the size by the port and flow step: 200 through 600, here size 300 with PT3/8 ports; step up a size when your demand sits near the top of a smaller unit's curve. This model carries the 5 um element instead of the 40 um standard - pick 5 um where downstream valves, cylinders or instruments need finer air. The automatic drain vents collected condensate without manual attention; manual and differential-pressure drains are the alternatives in this family. The round external gauge reads in psi (MPa and bar scales are order options), and the low-pressure regulator type suits circuits set below standard line pressure - we confirm its exact adjust range from the datasheet on request. PT thread is standard on this model; G (BSPP) and NPT are order options, and the mounting bracket is included. Because flow is published as curves rather than one rated figure, send us your flow and pressure requirements and we will confirm the right size before you order.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes G-series flow as curves rather than a single rated figure, so we do not quote one number here. Send us your required flow and working pressure and we will confirm against the GFR300 datasheet whether this PT3/8 unit is correctly sized for your application.
The W selects the 5 um filter element instead of the 40 um standard. Choose 5 um where finer air is needed for sensitive valves, instruments or finishing processes; the 40 um element remains the standard choice for general plant air. Both grades are available across the GFR range, and this unit also carries the automatic drain and the low-pressure regulator type as its other code-selected options.
